All right. Here is my first question to throw around to everyone: "Why am I not Roman Catholic?" (of course, if you are, help us understand why you are and why we should be(?)) Sounds like an easy question, but not so easy. Let me ask a few penetrating questions to get us going. These are all questions I've heard in different forms...
Does Christ not have only one church?
Does Rome not have the only consistent historical connection to the early church?
Did not Rome determine the new Testament cannon of Scriptures?
Does not Rome have what so many evangelicals lack: mystery, awe, contemplation, etc.?
One more, does our theology go asunder so irreparably?
Consider these Evangelical favorites: J RR Tolkien, G K Chesterton, and Mother Theresa. Are they not a sterling model of Christian imagination, thinking and service?
Hope this gets some discussion going.
